My invention relates to lubricating systems for gasoline dispensing pumps.

The principal problem of owners of gasoline dispensing stations has been the lubrication of the dispensing pumps. Pump mechanism is required to be enclosed and, in order to get at the pump mechanism to lubricate it, it is necessary to disassemble the pump equipment at least once a week which is not only expensive and laborious but is a task which filling station attendants fail to carry out with consequent inaccurate registrations due to wear of the pump parts.

This leads to difficulty with the customers 11.1; and municipal and state laws for inaccurate registration.

It is the object of my invention to provide a lubrication system particularly adaptable to gasoline filling station dispensing pumps 29 which can be operated from a common source, which will not necessitate dismantling of the pump and which will insure, by reason of the ease of its operation and the visible character of a system for inspection, a proper luiii brication of the pumps by filling station attendants. By observation of the oil reservoir by the inspectors from time to time, it will be possible to have a check upon the operation of the system and the application of lubri- 39 cant by the attendant.

Referring to the drawings:

Figure 1 is a side elevation of a portion of the pump mechanism with the cover removed showing the installation of the force 35 feed oil delivery system with visible reservoir and the piping conveying the oil to the essential parts to be lubricated;

Figure 2 is a section on the line 22 of Figure 1 looking in the direction of the arrows;

Figure 3 is a section on the line 33 of Figure 2;

Figure 4 is a section on the line 44 of Figure 1;

Figure 5 is a section through the rack roll, rack roll shaft and supporting mechanism.

Referring to the drawings, 1 designates the supporting frame work mounted upon the 7 base 2 of a gasoline filling station pump. The base 2 forms the head of the cylinder of the pump that is not shown as it is not necessary for the purpose of illustration of this invention. 3 designates a piston rod of the pump connected by the bracket 4 to the rack 5 which operates in the usual manner the gearing within the casing 6 that is attached to the frame 1. 7 indicates the setting stops which regulate and determine the movement'of the pump for the delivery of the desired quantity of liquid. 8 is a delivery pipe connected to the cylinder head 2.

Mounted upon the delivery pipe 8 by detachable clamping mechanism consisting of a permanent jaw 9 and a swinging 1O pivoted thereon at 11 is the force pump 12 with which the jaw 9 is integrally formed. The jaw 9 also serves as a distribution manifold having therein an arcuate passageway 13 which is adapted to communicate with any number of delivery pipes. These pipes are arranged to be taken off from the passageway 13 from either the top or the bottom thereof, thus facilitating the use of a plurality of such pipes in the restricted area that is available. These pipes as shown are five in number but any number may be employed. The pipe 14 leads to the handle gearing, the pipe 15 leads to the rack roll 25a which guides the rack, the pipe 16 leads to the indicator dial bearings. The pipe 17 leads to other indicator dial bearings. One branch 18 of the pipe 15 leads to the gearing bearings, intermediate the handle gearing and the indicator dial mechanism a descending pipe 19 discharges into a cupped reservoir 20 of the packing sleeve around the piston rod 3. The oil leaks down the piston rod into the oil reservoir 21 within this packing sleeve 22. The pipe 15 is connected by a T 23 on one side to the pipe 18 and the other side to an oiling reservoir 24: in the shaft 25 of the rack roll. The operating handle 26 is mounted within a sleeve 27 in one end of which it is supported. This sleeve is provided with an oil reservoir 28. A packing 29 is located adjacent the cooperating faces of the crank handle shaft sleeve 30 on the crank handle shaft 31 and the bearing portion of the cup shaped sleeve 2. I

A spring 32 engaging with the sleeve 27 and with a shoulder 33 of the sleeve serves to keep the shoulder 33 against a packing 34 to seal the oil reservoir with respect to the supporting plate 46 of the housing. The housing itself is provided with a supporting plate 35 with the sealing washer 36. A passsageway 37 communicates with the oil reservoir 28 on one side and with an internally disposed passageway 38 on the other side that leads to the pipe 14 which is connected *ithin a supporting plate 39 for delivery of oil to the passageway 38 and the chamber 28. The shaft 40 which is so supported in 39 is con nected to the shaft 31 and carries a gear 41 which meshes with the gear 42 on the shaft 43 that provides the intermediate connection between the handle and the indicating dial. The shaft 43 is provided with an internally disposed passageway 44 connected at one end to the pipe 18 which is mounted within the bracket 45. The bracket 45 and the plate 39 are mounted upon the casing supporting plate 46. Reservoirs for oil are formed between the plates 45 and 39 respectively and their shafts 43 and 40 in which oil can accumulate. The reservoir between shaft 40 and plate 39 is designated 47 while the reservoir between the bracket plate 45 and shaft 43 is designated 48. This reservoir communicates with and permits the lubrication of the ball bearing 49 that supports the right hand end of the intermediate shaft 43. The passageway 44 carries lubricant to a second ball bearing 50 at the other end of the shaft 43 where the shaft is supported by the ball bearing in the plate 46. The indicator shaft 51 is supported at one end in the bracket 45. This bracket support is provided with an enlarged chamber 52 which receives lubricant from the pipe 16. The shaft 51 carries the usual pointer 53 traveling over the dial 54 carried by the bracket 45. The other end of this shaft has a ball bearing support 55 which is lubricated by the pipe 17.

The entire system which is fed from the manifold 13 secures its oil from the visible oil reservoir 56 which feeds by gravity to the cylinder 12 in which operates a hand-operated piston 57 on a piston rod 58 carrying a hand push button 59 on the outer end thereof. This piston works against a spring 60 which serves to return it to its normal position which is inoperative. A ball check valve 61 is located at the outlet end of the cylinder 12. The return of the piston to the right hand serves to draw in a charge of oil into the cylinder while the movement of the piston to the left hand will discharge the oil into the manifold 13 and thence under pressure to the several delivery pipes.

The use of the oil for lubrication can be determined by an inspector by observing the quantity of oil which is being used up in a given period in the reservoir. The attendant merely swings the door or cover plate 62 to one side and presses the button 59 down to where it engages with the cylinder 12. This simple operation can be carried out at regular intervals, such as once a day.

Gas dispensing station equipment presents a peculiar problem for lubrication in that it cannot be disassembled as ordinary machinery for lubrication to such an extent that it may upset the registration of the alignment of the parts or so as to break the seal of the Government inspector who has officially approved its measuring adjustment. Hence, it is dificult to apply lubrication in the ordinary sense, which problem is obviated by my invention which permits of the application of lubricant where desired under pres sure by a simple operation. In the event the inspector has doubt as to the apparatus being properly lubricated it is a very simple matter for him to operate the system himself to insure that it is lubricated.

In an ordinary filling station having an average of live pumps, it requires an hour a week per pump to carry out the lubrication of the pumps if ofiicially done by an expert. This expensive labor and likelihood of not being attended to at all is eliminated by my invention without the danger of disturbing the adjustment of the mechanism by having to get at it in some fashion to lubricate it according to the old system.

A further advantage of my invention is its attachable nature. It may be attached in any position on the pump, is adaptable to existing pumps, can be placed in a position where the reservoir can be seen and the handle operated and, in the event of the pipes becoming stopped for any reason, they can be independently detached Without disturbing the rest of the pumps, or the whole system may be quickly removed and a new system installed in its place, the repair of the system being carried out by the manufacturer at its factory.

It will be understood that I desire to comprehend within my invention such modifications as may be necessary to adapt it to varying conditions and uses.
